DEPROVED BED-BOTTOM woj The Schedule referred to fn these Letters Patent and making pan: of the same.

To all whom 'it ma/y comm:

Be it known that I, CHARLES A. BRIGHAM, of Cleveland, in the county of Cuyahoga, and 4State of Ohio, have invented certain new and useful Improvements in Bed-Bottoms; and I do hereby declare that the following is a full and complete description of the same, reference being had to the accompanying drawings, making part of this specilication, in which- Fgure 1 is a top view of the bed-bottom.

Figure 2 is a view of the side.

Like letters refer to like parts in the different views.

The nature of this invention relates to a bed-bottom so constructed, that the slats ,of said bottom are made up in sections, and joined to each other by means of a exible joint. whereby the slats readily adjust themselves to the weight of the person lying thereon.

, In g. 2, A B represent the upper and lower slats of the bed-bottom, between which are arranged the springs C, said 'springs being attached to the upper and lower slats, and by which the upper ones are supported, and the bed receives therefrom the resiliency of the springs.

It will be observed that the upper slats A are constructed in four sections, more orless, may, however, be used, and that they are connected to each other by a hinge, a, attached to the under side of the slats, so that on. pressing down upon them, the slats yield to the pressure more or less, as the Weight may be upon them.

Bed-bottoms as ordinarily constructed, have slats of one entire piece, secured at each end to the bed-frame, or supported upon springs, as the case may be.

The objections to slats of one piece are that they do not yield or adapt themselves to the weight and curvatures of the different parts of the body, as the head, shoulders, and limbs.

Hence, a person stretched upon the bed, does not receive the full effect of the springs proportionally upon .each part of the body, as the entire slat is depressed or elevated at once, therefore the springs are of little value in a bed-bottom, in consequence of the rigidity of the slats, and more especially is this the fact, when the slats are arranged lengthwise the bed.

In making the slats in sections, more or less in number, and connecting themto each other, as above described, the entire arrangement of the upper slats becomes much more llexible, thus yielding readily to the various weight of the body, the section of the slat under the head yielding less than those under the shoulders and body, and the sections under the limbs the least.

This adaptation of the slats, makes the bed much more easy and comfortable, and can be used with much thinner mattress with equal comfort, than a bottom provided with entire slats.

This bottom although intended especially for beds, is equally adapted to sofas and lounges, having in them all the advantages secured to a bed.

. In the end-Slat sections, are slots a, to allow the slats to move longitudinally, as may be required in the springing of the sections, and through the slots pass the pins, or screws to hold the slats in place on .the block b, or bed-frame.

cure by Letters Patent, is-

.Ihe sectional slats A, jointed together so as to form alternate joints and Slat-sections transversely, in combination with the springs C and slots a, as and for the pulpose substantiallyas set forth.
